Question 1

What does sitemap validation check for?

Accepted Answer

Our validator checks your sitemap's XML structure, URL count (max 50,000), file size (max 50MB uncompressed), accessibility, and whether it's declared in robots.txt. We also analyze individual URLs for issues like invalid formats, missing required fields, and incorrect priority values.

Question 2

What are the most common sitemap errors?

Accepted Answer

Common errors include exceeding the 50,000 URL limit, incorrect XML formatting, missing namespace declarations, including non-canonical URLs (redirects, duplicates), using relative URLs instead of absolute URLs, and forgetting to declare the sitemap in robots.txt. Our tool flags all of these automatically.

Question 3

How do I fix validation errors found by this tool?

Accepted Answer

Address issues based on severity: critical errors (XML formatting, URL structure) should be fixed immediately, while warnings (missing lastmod dates, no compression) can be addressed gradually. Most errors can be fixed by regenerating your sitemap with proper absolute URLs, removing redirects, and ensuring valid XML structure.

Question 4

What are sitemap index files and when should I use them?

Accepted Answer

A sitemap index file is a parent sitemap that lists multiple child sitemaps. Use one when you have more than 50,000 URLs, want to organize URLs by category (blog, products, pages), or your sitemap exceeds 50MB. Each child sitemap can contain up to 50,000 URLs.

Question 5

How often should I resubmit my sitemap to Google?

Accepted Answer

You typically only need to submit your sitemap once to Google Search Console. After that, Google will automatically check for updates. However, if you make major structural changes, add thousands of new pages, or move your sitemap location, it's good practice to resubmit or ping Google about the update.

Question 6

Why is my sitemap not being crawled by search engines?

Accepted Answer

Common reasons include: sitemap not declared in robots.txt, incorrect sitemap URL, XML formatting errors, server returning wrong content-type header (should be application/xml or text/xml), 404 or 500 server errors, or robots.txt blocking the sitemap file itself. Use our validator to identify these issues.

Question 7

Should I include images and videos in my sitemap?

Accepted Answer

Yes, you can extend your sitemap with image and video tags to help search engines discover and index your media content. This is especially important for image-heavy sites (e-commerce, portfolios) or video platforms. You can include these in your main sitemap or create separate image/video sitemaps referenced in a sitemap index.
